# --description--
|
|
|
|
Os métodos do D3 podem adicionar estilos às etiquetas das barras. O atributo `fill` define a cor do texto para um nó `text`. O método `style()` define as regras do CSS para outros estilos, como `font-family` ou `font-size`.
|
|
|
|
# --instructions--
|
|
|
|
Defina o `font-size` dos elementos `text` para `25px` e a cor do texto para "red" (vermelho).
|
|
|
|
# --hints--
|
|
|
|
As etiquetas devem ter a propriedade `fill` com a cor "red".
|
|
|
|
```js
|
|
assert($('text').css('fill') == 'rgb(255, 0, 0)');
|
|
```
|
|
|
|
As etiquetas devem ter um `font-size` de `25` pixels.
|
|
|
|
```js
|
|
assert($('text').css('font-size') == '25px');
|
|
```
